Help me out here - as someone who was just a toddler when Joe Cocker came on the scene: What is it that made people bother listening to him?

Is it the 'gawker' effect? That is, there's a car accident on the road and you rubberneck, even though you tell yourself you're not going to do it? Were people just waiting for him to punch himself in the face?

I don't get it, but the video was ace!
